The Skin Aging Biology
Skin aging involves declining collagen production (falls approximately 1% per year after age 20), reduced hyaluronic acid synthesis, decreased elastin integrity, and accumulated oxidative damage. Each of these processes represents a potential therapeutic target for peptide-based interventions.
GHK-Cu: The Gold Standard for Skin Peptides
GHK-Cu has the most developed research base of any peptide for skin applications. In vitro studies consistently show fibroblast stimulation, collagen synthesis upregulation, and glycosaminoglycan production. The 2012 gene expression study showing modulation of over 4,000 skin-related genes suggests a broad mechanism that may explain why clinical results are often meaningful.
BPC-157 and Skin Research
BPC-157’s skin research is less developed than GHK-Cu but includes wound healing studies showing improved skin closure rates. Its role in angiogenesis and growth factor signaling could theoretically support skin health, but this is further from established evidence than GHK-Cu’s direct collagen-stimulating effects.
What a Physician-Prescribed Skin Protocol Looks Like
My Body Labs’ Skin and Collagen protocol centers on GHK-Cu as the primary compound. A physician evaluates your skin health goals and history before designing a specific protocol. Outcomes are assessed over 8-12 weeks with the physician reviewing progress and adjusting as appropriate.
